Datenschutz stellt eine große Herausforderung für die Entwicklung von Informationssystemen dar. Obwohl viele Konzepte zur Wahrung des Datenschutzes bestehen, werden Datenschutztechniken in der Regel nicht in Datenbankmanagementund Assistenzsysteme integriert. In diesem Artikel stellen wir eine SQL-Implementierung des Slicing-Konzeptes von Li et al. [10] vor. Es erfolgt eine detaillierte Betrach...
Sistemas Multi-Agente Robóticos MAD-Smart y se desarrollan algunos ejemplos para visualizar algunas de sus características. La metodología buscar dar cobertura en la fase de conceptuación, análisis y diseño mediante la definición de un conjunto de actividades que ayudan al desarrollador a entender mejor el problema a resolver, las características finales que deberá tener el sistema y el papel q...
There is a need for a brief specific measure of anger for use in assessment of posttraumatic mental health problems. One unpublished short scale is the Dimensions of Anger Reactions (DAR; R. Novaco, 1975). This study examined the psychometric properties of the DAR using intake and 12-month data for 192 Australian Vietnam veterans with combat-related PTSD. Results showed the DAR to be unidimensi...
The D2 dopamine receptor (D2 DAR) is one of the most validated drug targets for neuropsychiatric and endocrine disorders. However, clinically approved drugs targeting D2 DAR display poor selectivity between the D2 and other receptors, especially the D3 DAR. This lack of selectivity may lead to undesirable side effects. Here we describe the chemical and pharmacological characterization of a nove...
The antiviral RNA-dependent protein kinase, PKR, binds to viral double-stranded RNA in the cell and halts protein synthesis by phosphorylating the alpha subunit of the translation initiation factor eIF2. In this issue of Cell, two complementary papers Dar et al. (2005) and Dey et al. (2005) address the interaction between PKR and eIF2alpha. The structures of eIF2alpha bound to PKR reveal that P...
Dialect speakers in the North of England use vowel-less forms of the definite article (the) which are unattested in English varieties elsewhere and have been termed Definite Article Reduction (DAR). Previous research on DAR has provided detailed phonological descriptions, but less insight has been gained into other aspects of DAR like its emergence and the northern pattern of occurrence. I demo...
Studies involving lambda phage transduction of the D-arabinose utilization gene (dar+) in Escherichia coli K-12 indicated the product of this gene to be a transdominant activator. An apparent anomaly regarding this hypothesis exists in that a diploid recessive lysogen (lambda dar-/dar-) can spontaneously become capable of growth on D-arabinose.
Obwohl die Notwendigkeit zur didaktischen Durchdringung von Lehrbzw. Lerninhalten (i.e. Content) im e-Learning mehrfach betont wird (vgl. z.B. Euler 1992, Schulmeister 2001), ist dies methodisch allerdings kaum in technologisch orientierte Entwicklungskonzepte integriert. So definiert beispielsweise Schulmeister die Qualität der didaktischen Materialien als oberstes Qualitätskriterium virtuelle...
